For example, in Windows server computer, the directories can be the entities. The directories can be defined by parameters such as the disk-occupied size in bytes, directory location in the computer, and user privileges to access. The fields such as diskspace, location, and users can be used to define the directory parameters.
Fields are an integral part of the entity schema for defining an asset type. In an entity schema, fields are defined for an entity. An entity can contain as many fields as are required to define the asset type. A configured data collector collects data for the fields that are specified in the entity schema.
